PATENT LOCK.

SPECIFICATION forming part of Letters Patent No. 271,662, dated February6, 1883,

Application filed March 23, 1882. Renewed November 23, 1882. (Model.) i

Be it known that I, SOLOMON P. STODDARD,

i of the city, county, and State of New York,

have invented an Improvement inLoclis, of which the. following is afull, clear, and exact description, reference heilig had totheaccompanying drawings, forming partof this specification.

My invention relates to a lock in which th bolt-piece is constituted andarranged in two or more sections orparts,which,when the bolt is shot,are protracted sidewise, thus causing the bolt end to become spread; andmy invention consists in the devices hereinafter specified, and combinedto operate as and for the purpose described. Figure l is a side view ofalock containing my invention, the bolt being shown retracted and theside plate removed. FigV 2 is a similar view of the same, the bolt beingshown shotanditssectionsprotractedsidewise. Figs. 3 and 4 are sideviews, in detail, of the sections constituting the bolt-piece detachedfrom the boltplate.

In the drawings I have shown a lock the actuating mechanism ot'which isfully described and claimed by me in Letters Patent of the United StatesNo. 254,402, dated February 28, 1852, consisting substantially in thetumblers A, the boltplate B, carrying the rack b, and theoperating-pinion C, with its peculiar keyslot c, the several parts beingcombined orarranged relatively to each other in the manner thereinrecited. It is not necessary', therefore, in this specification to domore than naine the parts of this actuating mechanism, and to refer tothe aforesaid patent for a more full description thereof. Moreover, Ido'not intend to limit myself' herein to the specific actuatingmechanism shown, as my improvement is capable of use in connection withother kinds ot' lock mechanism.

My improvement consists in the bolt-piece D, which I form in two or moresections, d d, coincident in general form and outline, and imposed oueupon another, as shown. When thus arranged they are of substantiallyequal width with the width of thebo1t-plateB,andin thickness they areadapted to enter and traverse freely through the bolt-slot in theface-plate of the lock-case. The several sections of the thereof.

' bolt-piece are pivoted by a pin, d', which is common to all thesections, to the forward end of the bolt-plate, so that the sections arecapable of swinging edgewise on said pivot. In u each of the sectionsofthe bolt-piece is cut the longitudinal slot d2, whichextends in aright line from a point adjacent to the forward end of the section tonear the rearward end of the section, where the slot is inclined orcarried at an angle to one side of said line, forming acurved orobliqueheel portion, da, to the slot, as seen plainly in Fig. 3. These portions'd3 of the slots d are carried or turned alternately to one side and theother ofthe median line ofthe slots in the several sections of thebolt-piece-that is to say, the portion clgof the slot of the uppersection of the bolt-piece being inclined to the' right, the portion laof the slot of the section underneath is inclined in the oppositedirection,'or to the left, and so on throughout the sections. Theseslots cl2 throughout their extent are adapted to receive a pin, d, whichis tixed in the interior face of the lock-case, and which projectstherefrom through the several sections of the bolt-piece.

rIhis pin d4 is set inthe look-case so that the position of itsprojecting end relativelyv to the slots d2 will be such that when thebolt is retracted the pin will lie in the forward end of the slots, asseen in Fig. l, and when the bolt is shot the pin will rest snuglyagainst theinclosing-edges of the slots in the portion di In thedrawings I have shown a holt-piece composed of two sections; butitisevident that more than two sections may be employed to make up thebolt-piece without materially altering the essential features of myinvention. Now, it is evident that when the bolt is retracted thesections ofthe bolt-piece will rest coincidently one upon theotherwithin the case, the pin d4 lying in the forward end of the slotsd2, and that when the bolt is shot the pin d* will traverse in thevslots d2 in the forwardly-moving bolt-piece until the rearward end ofthe straight part of said slots is reached, when the further forwardmovement ot' the bolt-piece will cause the pin d4 to enter the inclinedheel portionsdof the slots d2, and thus throw or protract the severalsections of the bolt-piece n alternately opposite directions edgewise,and so that they project sidewise beyond the lines 0f the bolt-plate, asshown plainly in Fig. 2, and tl1at,rhe vpin d4 fitting snugly within theportion d3 of the slot, the strain npon the bolt-piece will be wholly oralmostwholly borne hy said pin, and the pivot d will be relieved of allor nearly all strain.

The lock which I have shown and described is peculiari)1 adapted for usein securing the lids ol' boxes and in siinilar structures.

What I claim as my invention, and desire to secure h v Letters Patent,is"

In a lock, the combination, with the actuating mechanism, including abolt-plate, B, of
